This arrangement of the scales gradually assumes a uniform appearance on the neck close to the head, where they are ovate.

Head rather long with nine plates, frontal plate being divided; the snout very blunt, truncated; the upper central labial scale octangular, with a deep concavity on the labial margin; the anterior and posterior mental scales long.

The tail one-fourth the length of the body, covered with uniform ovate quadrangular scales.

Length, four feet.
This species appears to have a considerable affinity to the genus named Macrosoma by Dr.Leach, but not described by him, and is very much like Coluber decorus of Shaw.

It belongs to the group called by English Zoologists, Whip Snakes.
The specimen above described was taken by Mr.James Hunter, at Careening Bay, on the north coast, and presented by him to the British Museum.
